Fresh oca roots, also known as New Zealand yams, are vibrant, tangy tubers prized for their unique flavor and crisp texture. Proper storage is essential to preserve their earthy goodness and ensure they remain a delightful addition to your culinary creations, from roasted dishes to fresh salads and stir-fries.
Storage Time
1-2 weeks in a cool pantry, 2-3 weeks in the refrigerator, or up to 6-8 months when properly frozen.
Temperature
For optimal freshness and to maintain their crisp texture, store fresh oca roots in the refrigerator at a cool 0–4°C (32–40°F). If storing in a pantry, ensure it's a cool, dark, and well-ventilated area.
Freezing
Yes, fresh oca roots can be successfully frozen to extend their shelf life significantly. To prepare them for freezing, first wash and gently scrub the oca roots, then peel them if desired. Blanch the whole or sliced oca in boiling water for 2-3 minutes to help preserve their texture and color. Immediately transfer them to an ice bath to halt the cooking process, then drain thoroughly and pat completely dry. Flash freeze the blanched oca on a baking sheet until solid, then transfer to airtight freezer bags or containers, removing as much air as possible to prevent freezer burn. Label with the date. When ready to use, thaw frozen oca in the refrigerator overnight or cook directly from frozen, though the texture may be slightly softer after thawing.
Signs of Spoilage
- Soft or mushy spots: A clear indication that the oca roots are losing their firm, crisp texture and beginning to break down.
- Mold growth: Any visible fuzzy patches, especially around blemishes or ends, signify spoilage and the roots should be discarded immediately.
- Unpleasant odor: A sour, musty, or off-smell, distinct from their natural earthy aroma, means the oca roots are no longer fresh and safe to consume.
- Significant shriveling or wrinkling: While some minor dehydration is normal over time, excessive shriveling suggests the roots are past their prime and have lost too much moisture, impacting their quality.
